Wow thanks for all the trouble you guys went to, I think I've understood most of it, just a couple of questions though...
Lurk R, What do you mean I'll have to ensure that I have a data line connected? is this something I have to ask for when I sign up?
I had intended to buy the phone (sim unlocked) no contract, pay as you go, and simply use it as a remote modem to dial my internet account, are you telling me I'll have to ask for something specific?
If its going to be too difficult I'll just leave it and wait until I get home.
